Recently, I found a small but big new bug in R 2.0.1.
Korean Language is shown as broken in R Gui terminal.
R 1.9.1 had not the problem, but R 2.0.1 makes the
problem. Korean is one of 2-byte character system,
and is supported in Unicode (of 3 byte). I don't know
why new version of R makes new problem.

Please fix this bug for all Korean using population, more
than 1/60 of the world population.

If you need more detail report, please ask to me via e-mail.
If you let me know your address, I can send the pictures
illustrating the bug.
